CVE-2026-34120
6.5 · MEDIUMOverview
CVE-2026-34120 is a medium-severity vulnerability affecting tp-link tapo_c520ws_firmware. It was published on April 2, 2026 and has a CVSS 3.1 base score of 6.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within the asynchronous parsing of local video stream content due to
insufficient alignment and validation of buffer boundaries when processing streaming inputs.An attacker
on the same network segment could trigger heap memory corruption conditions by
sending crafted payloads that cause write operations beyond allocated buffer
boundaries. Successful exploitation
causes a Denial-of-Service (DoS) condition, causing the device’s process to
crash or become unresponsive.
Remediation
Check the references section for vendor advisories and patches from tp-link. Update tapo_c520ws_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
